Welcome to TeX.SX! In "Options" -> "Save profile..." you can save a profile file in a location of your choice which will be the mentioned .texsprofile. Edit this file, and add the part mentioned in the answer you linked to. Then "Options" -> "Load profile..." does what you think it does.

Thank you for letting me know where the file ` .tsxprofile` should be. but in the default, my TeX Studio does not be endowed such file .tsxprofile. So, I try to make a file .tsxprofile and try to load it. but it does not goes well. I try tomorrow.
